Explanation:

1. Passive transport does not require energy. So the answer is D.
2. Kinetic energy is the energy of motion. So the answer is A.
3. Diffusion is the movement of substances from an area of high - concentration to an area of low - concentration. So the answer is B.
4. When solutions are in equilibrium across a selectively permeable membrane, the solutes and solvents move back and forth equally. So the answer is C.
5. Water uses aquaporins to move across a selectively permeable membrane in facilitated diffusion. So the answer is A.
6. Solutes move across the phospholipid bilayer by simple diffusion. So the answer is D.
7. When too much water leaves a cell, it will shrink. So the answer is D.
8. Active transport uses cellular energy, while passive transport does not. So the answer is C.
9. Living things use ATP as energy. So the answer is C.

4. C. the solutes and solvent move back and forth equally.
5. A. facilitated
6. D. simple
7. D. It will shrink.
8. C. Active transport uses cellular energy, but passive transport does NOT.
9. C. ATP
